Abstract Closing both the carbon and nitrogen loops is a critical venture to support establishment of circular, net‐zero economy. Although single atom catalysts (SACs) have gained interest for electrochemical reduction reactions dioxide (CO 2 RR) nitrate (NO 3 RR), structure–activity relationship Cu SAC coordination these remains unclear should be explored such that fundamental understanding developed. To this end, role structure investigated in dictating activity selectivity CO RR NO RR. In...
Abstract 2D metal organic frameworks (MOF) have received tremendous attention due to their organic–inorganic hybrid nature, large surface area, highly exposed active sites, and ultrathin thickness. However, the application of MOF in light‐to‐hydrogen (H 2 ) conversion is rarely reported. Here, a novel [Ni(phen)(oba)] n ·0.5 H O (phen = 1,10‐phenanthroline, oba 4,4′‐oxybis(benzoate)) for first time employed as general, high‐performance, earth‐abundant platform support CdS or Zn 0.8 Cd 0.2 S...
Abstract Direct experimental observations of the interface structure can provide vital insights into heterogeneous catalysis. Examples design based on single atom and surface science are, however, extremely rare. Here, we report Cu–Sn single-atom alloys, where isolated Sn sites with high densities (up to 8%) are anchored Cu host, for efficient electrocatalytic CO 2 reduction. The unique geometric electronic alloys (Cu 97 3 99 1 ) enables distinct catalytic selectivity from pure 100 70 30...
High-performance and low-cost photocatalysts play the key role in achieving large-scale solar hydrogen production. In this work, we report a liquid-exfoliation approach to prepare NiPS
Modulating the electronic structure of atomically dispersed active sites is promising to boost catalytic activity but challenging achieve. Here we show a cooperative Ni single-atom-on-nanoparticle catalyst (NiSA/NP) prepared via direct solid-state pyrolysis, where nanoparticles donate electrons Ni(i)-N-C network carbon nanotubes, achieving high CO current density 346 mA cm-2 at -0.5 V vs RHE in an alkaline flow cell. When coupled with NiFe-based anode zero-gap membrane electrolyzer, delivers...
Demonstrating the potential of electrochemical carbon dioxide reduction reaction (CO2RR) in industrially relevant conditions is a promising route for achieving net-zero emissions through decarbonization. This requires catalyst system that displays not only high activity and stability but also capacity to deliver consistent performance presence waste stream impurities. To explore these opportunities, we investigate role Ni coordination structure plays on impurity tolerance highly active...
An ultra-thin indium tin oxide interlayer design was developed for interfacing perovskite solar cells with Si thereby minimising shunting effects large area monolithic tandem devices.
Here we report for the first time a monolithic perovskite–CIGS tandem (CIGS = Cu(In,Ga)Se2) solar cell on flexible conductive steel substrate with an efficiency of 18.1%, highest to date, representing important step toward perovskite-based photovoltaics.
Controllable concomitant production of CO and H2 (syngas) during electrochemical CO2 reduction reactions (CO2RR) is expected to improve the commercial feasibility technology mitigate emissions as generated syngas can be converted into useful chemicals using Fischer-Tropsch (FT) process. Herein, we demonstrate ability a Co single-atom-decorated N-doped graphitic carbon shell-encapsulated cobalt nanoparticle electrocatalyst (referred Co@CoNC-900) controllably produce at low overpotentials...

Through heat treatment commercial-grade nitrogen-doped graphene, prepared defective which was then used as platform incorporate single atoms via carbon defect restoration, confirmed by range characterization techniques. We reveal that these Ni-hG...
The development of highly active and reliable photocatalysts for solar hydrogen (H2) production requires the thorough in-depth understanding atomic-level structure/composition-performance relationship in photocatalysts. In this contribution, we first time develop a new simple technique to prepare ReS2 ultrathin nanosheets (UNSs) with massive edge sites. atomic-resolution scanning transmission electron microscopy integrated density functional theory (DFT) based computations predicts that...
Heterogeneous molecular catalysts built from β-substituted cobalt porphyrins and carbon nanotubes afford tunable activity for H 2 O synthesis via the two-electron transfer oxygen reduction reaction.
Abstract High bandgap perovskite solar cells are integral to perovskite‐based multi‐junction tandem with efficiency potentials over 40%. However, at present, high devices underperform compared their mid counterparts in terms of voltage outputs and fill factors resulting lower than ideal efficiencies. Here, the low factor aspect is addressed by developing a cation‐diffusion‐based double‐sided interface passivation scheme that simultaneously provides bulk for 1.75 eV cell also compatible p‐i‐n...

Focused ion beam lift-out has become an essential technique for fabricating small-scale specimens in atom probe tomography (APT). By using a rotatable micromanipulator, we developed methods that can precisely extract the regions of interest APT samples with challenging-to-prepare geometries. Combining this function pre-milling and pre-tilt operations, prepare three typically challenging specimens: nanoparticles, nanowires, thin films. This combination effectively decrease sample preparation...
